Could not get HANA detailed monitoring No database instance configured - SAP LaMa

Could not get HANA detailed monitoring No database instance configured. Configure the Database instance name in the service configuration, e.g. HDB<Instnr>
Database has the following warning/error process
hdbalertmanager - HDB Alertmanager - SAPHostControl-DB-WARNING: alerts on database.

But I didn't find where can I configure the DB instance name.

Thank you.

Kind regards.

EDIT: OK, I found how to add the DB instance name, but when I add it (HDB02) it returns me the following errors:

HDB02 is the right instance, how can I modify the registry to correct the instance ID?
